Ultimately, Rachel isn't the only familiar face joining the cast of Nashville as a season regular. Empire star Kaitlin Doubleday has been brought on in the wake of Connie Britton's exit from the show.

"Music city, here I come #nashvillecmt," Rachel recently shared on Instagram when confirming the news. Chris later added, "Can't wait to work with Rachel again... it's been a while! ‘Welcome to Nashville....... darlin'!"

"We welcome Rachel and Kaitlin into our incredibly talented ensemble," Marshall Herskovitz, executive producer and showrunner, said in a statement to E! News. "We fondly anticipate the second half of the season filled with surprising twists and turns that make Nashville so beloved by the fans."
